PAPER-MAKIN MACHINE;

Application filed November s, 1927. Serial No. 231,830.

This invention relates to certain im rovements in paper making machines 0 .1 that class in which the web is formed on a making wire, such as a Fourdrinier machine.

In this class of machines, there is employedan endless forming wire which passes over a series of suction devices provided with perforations, the suction devices acting to remove water from the web during. the process" of its formation-as the wire and, web

. travel over these suction devices.

These suction devices are generally in the form of boxes, the-tops of which are usually of wood over which the wire slides, and the action of the suction boxes tends to draw the wire down against the tops of the boxes, so that the mesh of the wire tends to groove the tops of the boxes, thus increasing frictional resistance and causing trouble in actuating the forming wire.

It is the special object of the present in vention to provide means for causing the suction boxes to change their positions relatively to the wire so that the .wire will wear these boxes uniformly and prevent the un-' .desirabl'e' grooving above referredto.

A further object of the invention is to produce such a construction which shall j ings andth novel features pointe be of simple form and which may accomg:

plish its purpose without sacrificing any rigidity of the mechanism or preventing the mechanism from suitably functioning.

With these and other objects not specifically' referred to in view, the invention consists .in certain novel parts, arrangements and combinations which will be described in connection with the accompanying' draws .out in the claims hereunto appended.

clude vmeans for supporting the' suction boxes so that they may be moved relatively to the making wire, this movement being such that the supports for the suction boxes are reciprocated in opposite direction, thus causing a c ntin-uous angular" variation of the boxes wi h relation tothe' wire, together with means whereby the boxes may be given a slight sidewise or widthwise -movement."

with respect tothe'making wire, such move- -ment efiectmg a uniform wear of the boxes and-an efiectual preventing of thejundesiri able" groovin A preferred construction for effecting the Generally speaking, the invention will inrespectively, of certain details of construction in the mounting of the suction boxes.

Referring now to these drawings in detail, lindicates the breast roll of a Four-, dpmier machine, 2 the making or forming wire, and 3 the table rolls, these parts being supported in suitable framing 3, 4. The suction boxes, four of-which are shown, are

indicated at .5; 6 indicates the guide. roll,'

and-7 the-couch-roll, the wire returnin to the breast roll over suitable carrying-rolls 8,

this construction being common in Fourdrinier machines.

These suctlon boxes extend across the ma- Figures 6 and? are plan and side views,

chine, as shown, and in accordance with the invention means are. 'provided .lfo'r mounting these suction boxes so that they may be given an angular reciprocating movement and so that they may be given an endwise' or widthwise movement relativel to the wire, this latter movement prefera ly being simultaneous with the angular movement.

While the particular construction for eifecting this maybe somewhat varied, in the particular construction illustrated there is provided side framing. 9, 10, on which is sup ported a pair .of shding frames 11, 12. Supported onthese sliding frames, .at each side,

are standards 13 14 and 15, which support top bars 17, to w ich the suction boxes 5 are secured in any suitable manner, as by hanger bolts 18, these being shown in detail in Figures 5 and 6. "As there shown, the hanger b'olts'pass throu 'h plates 19 on the top bars 17, these plates beingpivoted on pivots 20,

slots 21 being provided in the plates so that the bolts may have a swinging movement in these slots for purposes hereinafter referred 4 These frames' llfl have a sliding movement on the side frames 9, 10, before referred *to, I andi'me'ans arei-provided for [reciproeating these frames-in opposite directions so as to effect an angular movement of the automatically. While various construct-ionsmaybe employed. for effecting this move- 'me'nt,= i n 'the particular construction shown I thisxmov'eme'nt' is-vefi'ected and .at the same time limited byzmeans of a screw rod 22 acting through a screw block or-nut23 suitably.

secured to. the under sideof the sliding frames 11, 12,- vbefore referred to, it being "understood that this construction is duplicated- .von=each side of the 'machine. The

screw rod 22.0n one side of the machine has a rightha'ndthread and on the other side .of the machine has a left hand thread. Therefore, by manipulating these screw rods the slides-11, 12 are-moved in opposite directions. As shown,, these' screw rods are operated by a cross shaft 24, which'is driven from a re'v,ersing inotor-25 through suitable speed reducing gears, indicated at'QQ in Figure 3. The drive from the shaft .24 to the scr ew-rbds' '22 'may be ofany suitable char water, this being illustrated as by means of belts 27 passing over pulleys 28 and pulleys 29 on each side of themachine, these last pulleys. being'mounte'd on aworm shaft 30, the worm 30 of which meshes with a worm wheel 31 on the outer end of the screw rod,

this construction being duplicated on each side of the machine.

Means areprovided for automatically reversing the motor to-reciprocate the frames in opposite directions, such means including a reversing switch 32,. which is -operated through a crank -33 and a rod 34 by stops 35- carried on .one of the sliding frames, as the frame 11-. r

With the construction so far described, it will be observed that the boxes are given an angular movement relatively to thewire,

and the angle ofthis movement is constantlychanging. 'While this gives good results, in the best practice of the invention means will also be provided for giving the boxes an additionalsidewise' or widthwise movement relatively to the wire, this movement .preferably being simultaneous with the 'movement by which the angular variation in the position of the boxes is effected. While thls may be accomplished in various ways,

in the particular construct-ion shown there are provided two sets of keys or splines 36, 37 and 38, 39 secured onthe main frames 9, 10,; these keys riding in grooves or slots formed on the under side ,of the sliding frames 11,112.. It will be observed that these keys are angularly arranged, the keys '1n scribed. flVith this combination .of move- 36, 37 pointing inwardly and the keys 38,

39, on the'opposit'e side of the machine, also pointin inwardly, With this construction, as the Frames reciprocate,- the .angularity of the keys andslots effects alimited sidewise orwidthwise'movement of the frames, this movement occurring during the reciprocatg or endwise movement heretofore dements, auniform-wear of the suctionwboxe s 1S effected and the ob ect1onable grooving of the tops of these boxes is effectually elim' inated.

understood that certain variations maybe The suctionboxes are connected to amai'n i made in the form and arrangement of the parts and the specific means described for effecting the desired movement ofzthe boxes without departing from the invention as defined in the appended claims;
